Limitations of augmentation index in the assessment of wave reflection in normotensive healthy individuals.

open access: yesPLoS ONE, 2013
ObjectivesAugmentation index (AIx) is widely used as a measure of wave reflection. We compared the relationship between AIx and age, height and sex with 'gold standard' measures of wave reflection derived from measurements of pressure and flow to ...

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Thin liquid film thickness measurement using stepped-index-type optical fiber sensors

open access: yesJournal of Fluid Science and Technology
Optical fiber liquid film sensors utilizing the reflection intensity at the gas-liquid interface exhibit excellent environmental robustness. However, this technique needs to improve its sensitivity when measuring liquid film thicknesses approaching the ...

Structural coloration and ultraviolet protective fabrication on fabrics coated with SiO/TiO multilayer films via a magnetron sputtering method

open access: yesJournal of Industrial Textiles, 2022
Interference structural colors and excellent ultraviolet (UV) protection performance were prepared by coating SiO 2 /TiO 2 composite multilayer film on polypropylene non-woven fabrics (PP-NW) and polyester woven fabrics (PET-W) via a magnetron sputtering

Attitudes of cancer patients toward ctDNA‐based liquid biopsy for follow‐up

open access: yesMolecular Oncology, EarlyView.
This mixed‐methods study explored cancer patients' experiences, knowledge, and preferences regarding ctDNA‐based liquid biopsy for follow‐up. Awareness of ctDNA was low and recall of previous liquid biopsy was imperfect, yet acceptance was high.

The Imperial Viceroy: Reflections on an Historical Type [PDF]

open access: yes, 2014
Empires are spatially extended polities of a composite and hierarchical nature. They have a monarch at the top or, in exceptional instances, a collective body such as an oligarchical senate, a politburo, or an elected republican government. This chapter focuses on that top echelon of peripheral governance which is indispensable for the running of ...

On the inverse braid and reflection monoids of type B [PDF]

open access: yesSiberian Mathematical Journal, 2009
There are well known relations between braid groups and symmetric groups, between Artin-Briskorn braid groups and Coxeter groups. Inverse braid monoid the same way is related to the inverse symmetric monoid. In the paper we show that similar relations exist between the inverse braid monoid of type $B$ and the inverse reflection monoid of type $B$. This

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
